Abstract (en)
[origin: EP1940205A2] A microwave circuit board includes: a board made of insulator; a metallic conductor to transfer an electric signal which is formed on at least one of a main surface and a rear surface of the board; and an electric power layer formed on the rear surface of the board and/or in the board. The board includes an dielectric constant-reducing mechanism so as to reduce an effective dielectric constant of the board.
